The value of life methodology has been recently applied to a wide range of contexts as a means to evaluate welfare gains attributable to mortality reductions and health improvements. Yet, it suffers from an important methodological drawback: it does not incorporate into the analysis child mortality, individuals’ decisions regarding fertility, and their altruism towards offspring. Two interrelated dimensions of fertility choice are potentially essential in evaluating life expectancy and health related gains. First, child mortality rates can be very important in determining welfare in a context where individuals choose the number of children they have. Second, if altruism motivates fertility, life expectancy gains at any point in life have a twofold effect: they directly increase utility via increased survival probabilities, and they increase utility via increased welfare of the offspring. We develop a manageable way to deal with value of life valuations when fertility choices are endogenous and individuals are altruistic towards their offspring. We use the methodology developed in the paper to value the reductions in mortality rates experienced by the US between 1965 and 1995. The calculations show that, with a very conservative set of parameters, altruism and fertility can easily double the value of mortality reductions for a young adult, when compared to results obtained using the traditional value of life methodology.

This paper explores the link between environmental policy and economic growth by employing an extension of the AK Growth Model. We include a state equation for renewable natural resources. We assume that the change in environmental regulations induces costs and that economic agents also derive some utility from capital stock accumulation vis-`a-vis the environment. Using the Hopf bifurcation theorem, we show that cyclical environmental policy strategies are optimal, providing theoretical support for the Environmental Kuznets Curve.

Em meio ao crescente volume de publicações sobre sustentabilidade e finanças, diversas pesquisas internacionais e brasileiras têm abordado a relação entre empresas classificadas como sustentáveis e o retorno de suas ações. Nesta mesma linha, este trabalho utilizou o método de estudos de eventos para verificar se entre 2005 e 2013 houve retornos anormais quando as empresas entraram e saíram do Índice de Sustentabilidade Empresarial (ISE). Além de contemplar um período mais atualizado do que seus precedentes, este estudo difere-se dos demais ao analisar o as observações individualmente e ao buscar estabelecer uma relação dos retornos anormais acumulados com as variáveis governança corporativa, tamanho, rentabilidade e alavancagem. Os resultados mostraram que embora não haja evidências conclusivas quando os casos são tomados individualmente, em conjunto eles indicam que a inclusão e a exclusão do ISE geram retornos anormais significativos, positivos e negativos respectivamente, em linha com a teoria dos stakeholders. Quanto às variáveis de controle, nenhuma apresentou relação com os retornos anormais acumulados.

Environmental policy affects the distribution of market shares if intermediate goods are differentiated in their pollution intensity. When innovations are environment-friendly, a tax on emissions skews demand towards new goods which are the most productive. In this case, the tax has to increase along a balanced growth path to keep the market shares of goods of different vintages constant. Comparing balanced growth paths, we find that an increase in the burden of environmental taxation spurs innovation because it increases the market share of recent vintages. As a result the cost of environmental policy in terms of slower growth is weaker and may even be absent.

This doctoral thesis is about global brands under several perspectives, starting this study with and overview on the matter, followed by a "step ahead" in the conceptualization of brand equity and brand value. As the global marketplace dynamically increases, there are theoretical and empirical challenges concerning the global brands that ask for more branding researches, trying to tune and to contextualize meanings and attributes. Thereafter, the thesis intends to provide a discussion about the industry and country-of-origin effects (and their interactions) on the brand value and the firm market value. Finally, the thesis offers an interesting comparison about the practitioners’ perspectives on the dimensions of global brands, the brand equity and the brand value, branding and marketing, including highlights on the brand internationalization process. The thesis offers a general approach on the extant literature in the first chapter, and a specific literature review for each other chapter.
